Calculate the LCM of 778,422,196,931

Given numbers are 778,422,196,931

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 778,422,196,931 is 305662196.

Find LCM of 778,422,196,931 with Prime Factorization


2 778, 422, 196, 931
7 389, 211, 98, 931
7 389, 211, 14, 133
389, 211, 2, 19

Multiply the prime numbers at the bottom and the left side.

2 x 7 x 7 x 389 x 211 x 2 x 19 = 305662196

Therefore, the lowest common multiple of 778,422,196,931 is 305662196.

LCM Formula to Find Lowest Common Multiple of 778,422,196,931

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

778 x 422 x 196 x 931 = 59909790416

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

778 : 1, 2, 389, 778

422 : 1, 2, 211, 422

196 : 1, 2, 4, 7, 14, 28, 49, 98, 196

931 : 1, 7, 19, 49, 133, 931

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,422,196,931, is 1.

Now, the common factors can be found like this.

778:2x 389

422:2x 211

196:2x 2x 7x 7

931:7x 7x 19

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 7x 7 = 196

Therefore, the value for common factors is 196.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 59909790416/(1x196)

LCM = 59909790416/196

LCM = 305662196

Thus, we can understand that the LCM of 778,422,196,931 is 305662196.
